Ponca tumor is a rare tumor disease from the group of benign skin diseases. Ponca tumors were first described by the American dermatologist V. Blake in 1896 under the name “osteatic tumors.” Most often, formations occur between the ages of 20 and 50, although formations can appear at a more mature age - after 70 years. The tumor is a characteristic formation - a slowly growing papule of regular shape, spherical or round (follicular).
